NINTH FLOOR.
The engraving lay against Martin's palm.
Tianheng Tower had eight floors. Every public plan, fire certificate and memory from nine years of commuting agreed on that. The brass key did not. Its inscription treated the ninth floor as neither anomaly nor secret, only an address the city no longer acknowledged.
His mother set the fourth cup back on the table. She no longer looked at the key, but her hand remained flat beside the empty place. Martin kept his promise not to ask about the incident again. He and Evelyn left the apartment with the burned ledger sealed between glass.
In the descending lift, the key felt colder than it had beneath the sofa tape.
Evelyn ignored the floor indicator. She was studying the recessed marks cut along both sides of the blade.
“These aren't normal teeth.”
“A door on a ninth floor might not take a normal key.”
“That's not what I mean.”
She placed it on the black notebook. Four groups of pits leaned towards the left edge, four towards the right. The ninth sat close to the bow, exactly between them. As a mechanical code, the depths offered too few combinations. As positions, they resembled a nine-square grid crushed into a strip of metal.
The engraving named the key's purpose. The spacing carried its coordinates.
In the car park, they borrowed a soft pencil from the guard. Evelyn covered the key with a receipt and rubbed sideways. The brass outline rose through the paper. Nine recesses appeared as dark ovals. The central one was deepest, with two short strokes beside it too fine to see on the metal itself.
Martin recognised the mark.
Early address-reconciliation work at the Municipal Data Consistency Center used paired strokes for a former survey origin. Before satellite coordinates, land numbers, pipes and street plans had all been measured outwards from one artificial zero. The symbol had vanished from current systems. Martin saw it now only when damaged title deeds were scanned for migration.
Evelyn rotated the rubbing until the strokes faced north. The nine marks resolved into three rows of three. At their centre, the deepest pit looked like a zero punched almost through the page.
“Where was the old survey origin?” she asked.
Martin already knew.
Where the two rivers met.
At 8:03, they parked at the edge of the old city. The rivers remained high after the rain. Water of two different colours approached beneath the bridges, their meeting traced by a restless seam across the brown surface. Pale arches showed between the trees. Farther back, glass towers sliced the sun into narrow white panels.
The tourists had not arrived. Cleaners worked along the promenade, collecting plastic cups washed in overnight. Pigeons lined the railing, all facing the same gap in the wind.
Evelyn took the rubbing and an offline street map to the viewing platform between the rivers.
The tourist map called it the historic heart of the city.
The cadastral map assigned the same platform to the eastern river authority.
An evacuation plan placed it on the west bank.
Tianheng's cached risk layer gave it no name at all. A grey ring surrounded the junction: NON-CALCULATION SURFACE.
Each map worked for its own purpose. None admitted that the place belonged to both sides at once.
“That's why it makes a good zero,” Evelyn said.
Not because there was anything mystical about a river junction. Every system needed a place from which to begin, and a boundary was easiest to define as belonging nowhere.
Martin aligned the key's central pit with the seam in the water. The eight outer marks did not land on fixed buildings. One pointed towards the communications tower, another towards the medical district. A third crossed the old archive quarter. The southern mark ended inside a pedestrian tunnel still under construction.
If the key was a compressed map of the city, the ninth floor was not a height.
It was permission to enter the ninth relationship position.
Evelyn opened the black notebook and copied every disappearance site whose time they could confirm from two independent records: the bus stop where a camera last reflected Hannah Teoh; the Safe Routes bus on which Ian Cheong became absent; the old apartment where Clara's fingers survived at the edge of a photograph; the café where Gavin Koo disappeared; the flyover an accident had avoided; the Missing Page Society; Wing Ming Photo Lab; Tianheng Tower.
Anything without a reliable minute remained off the map.
The first sheet of tracing film produced nothing.
The east side crowded with marks. The northwest stayed bare. Several anomalies fell across the edges of the nine squares. In a fixed grid, Wing On belonged to the archive quarter while Wing Ming fell into the neighbouring palace. The school-bus route crossed four of them by itself.
“Wrong scale?” Martin asked.
Evelyn tried three.
The points stayed incoherent.
She turned the map ninety degrees, considered it, and turned it back. The key pits described direction, not districts. North was not the error.
“We've been treating a palace as an address,” she said.
“What else would it be?”
“If the palaces were fixed, the same place should keep the same function. Tianheng Tower doesn't.”
She tapped the building on the map. When Martin received the call from his future number, the lift had opened the tower towards a ninth floor. Days later, the same building sealed records, revoked access and pressed every anomaly back into official form. One place had served first as an opening, then as a closure.
The gate had not remained inside the building.
Its effect had moved with the hour.
Evelyn started again. This time she separated the cases into two-hour windows. Midnight to two. Two to four. Four to six. Each sheet kept only the locations active during that interval, with the key's central mark fixed over the river junction.
Eight transparent layers covered the bench.
Wind lifted every corner at once. Martin weighted them with his phone, the blue pen and the brass key.
Evelyn aligned the three events after midnight and rotated their grid one position clockwise. Hannah's absence from the cameras settled in the southeast. Martin's route-less call moved due east. The Tianheng lift stopped in the southwest.
She turned the next layer two positions.
Wing Ming and the bus stop lay more than ten kilometres apart on the street map. Inside their time positions, they met on the same horizontal line. They were not the same district. They had performed the same act: briefly developing the image of a person being erased for someone else to see.
On the following layer, the direction reversed.
Gavin's empty coffee cup, the unoccupied chair at Wing On and the fourth cup in Martin's mother's apartment stood in three corners of the city. Rotated into their event positions, they enclosed one centre. None preserved a person directly. Each preserved the pressure of a relationship that had once occupied space.
Martin watched the lines close.
“The palaces are moving.”
“The city isn't,” Evelyn said. “Time changes what each place is allowed to do inside an event.”
She slid the earliest layer underneath. Streets that had overlapped pulled apart. A different set of locations approached from a new angle. North, south, east and west remained directions on paper. In this system, a palace described which people had been placed into the same structure and which actions the hour made easier.
A hospital could be an opening through which someone was saved. Two hours later, the same hospital could become the place where an error was sealed away.
A photo lab could restore a missing image. It could also supply the solvent rag used to burn an archive.
No gate produced the same outcome for every purpose.
Martin remembered Victor's warning in the old project material: do not mistake the gate for a place. The rubbings left by Evelyn's mother had carried the same instruction. They had treated it as advice for navigating corridors.
It described the whole city.
The nine palaces were not nine permanent pieces of Kuala Lumpur. They were a pattern that reassigned relationships every two hours.
Even the river junction was only a reference point. It was not the centre for all time.
Evelyn nudged the key's central mark away from the seam in the rivers. Every outer line lost alignment. She put it back, and the eight event groups closed again.
“Why would Victor choose this as the origin?” Martin asked.
“He needed a reference no administrative boundary could move.”
“Or Tianheng needed the real centre hidden inside a non-calculation surface.”
Both explanations fit. Nothing they possessed could tell them which had been the intent.
Martin did not select the kinder answer. Evelyn drew an empty box beside each.
At 9:21, the public-address system announced the river level. Malay first, then English. In the Mandarin announcement, the two river names were reversed. The next cycle corrected them. None of the cleaners looked up.
Evelyn recorded the time.
They had used Victor's pattern. The system had left a rough edge in response.
Martin opened an offline anomaly list copied from the Center. If Evelyn's rotating grid was real, ordinary data conflicts from the past month should also cluster by hour.
They selected nine events with no missing person attached: an electronic road sign displaying an exit that did not exist; a hospital queue number called twice; an extra face on an advertising wall; a parcel locker opening for the wrong customer; three car parks simultaneously losing their fifth floors.
Evelyn refused to see the outcomes in advance. Martin read out each time. She rotated the clear grid and marked only the positions.
The first four fell into different palaces.
The fifth and sixth began to align.
When she placed the ninth, the control events formed a second complete path. They did not circle one person. They followed whatever surface the city was most likely to notice, record and repeat at that hour.
Beside that path, Evelyn wrote VIEW.
Cameras, advertisements, information boards, public records. The surfaces everyone saw were also the easiest places for a correction to disguise itself as consensus.
“Can you project it forward?” Martin asked.
“The position, yes. Not the event.”
The pattern could tell them what kind of action would become easier next. It could not choose who would be present, what anyone would see, or whether Clara would be waiting at the end.
Evelyn laid down a blank sheet for the next interval. Following the previous six rotations, the View position would leave the media axis at ten and enter the northern transit band.
Three roads, a raised walkway and the Circle Line crossed that part of the map.
Martin eliminated the roads first. Their cameras had shown no repeated numbers in the last two hours. The walkway turnstiles were offline, leaving no active surface on which an image could spread.
The Circle Line met all three conditions. Hundreds of passengers watched its screens. Its carriages crossed several palace positions without stopping. Every platform used the same official clock to open and close the doors.
Evelyn opened an offline timetable. Seven trains would enter the northern section around ten. She wrote their full service numbers from left to right—not merely the endings—and compared their direction changes with the depths of the nine pits on the key.
Six sequences broke at the centre.
One continued from origin through transfer to destination.
R17.
It would leave Riverside Station at 9:58 and enter the northern tunnel at 10:04. At exactly ten, every advertising screen aboard would refresh.
Martin looked across the water. A silver curve of elevated rail appeared briefly between the towers. A test train moved along it without sound, its windows dividing the sun into consecutive white squares.
Evelyn wrote the time beside VIEW in the notebook.
10:00.
Thirty-seven minutes remained.
She looked up. “The next View Gate won't open at a station.”
“It will open on a Circle Line train already in motion.”
